[0002] The server is equipped with cables for signal transmission. To ensure the stability of the server, during the server development phase, it is necessary to perform performance tests on the cables used in the server to determine the insertion loss of the cables and to detect whether the insertion loss of the cables meets the performance requirements of the server for the cables. The insertion loss of the cable is the signal strength lost during the transmission of the signal through the cable.

[0003] In the related art, the cable testing scheme is usually as follows: controlling the tested cable to transmit a test signal of a specified frequency, measuring the insertion loss of multiple groups of test signals of specified frequencies during transmission through the tested cable, and then determining the insertion loss of the tested cable based on the average value of the measured insertion losses of each group, and detecting whether the insertion loss of the tested cable meets the performance requirements of the server for the cable. Test interference factors during the test process will cause insertion losses with large deviations in the measured insertion losses of each group. Test interference factors may include the internal noise of the instrument used and human factors during the test. The cable testing scheme of the related art does not consider the impact of test interference factors on the measured insertion losses of each group, and directly determines the insertion loss of the tested cable based on the average value of the measured insertion losses of each group. It is impossible to accurately determine the insertion loss of the cable, detect whether the insertion loss of the cable meets the performance requirements of the server for the cable, and the accuracy and reliability of the cable testing process are low.

[0058] Embodiment 1

[0059] Figure 1 A flowchart of a cable testing method provided in the first embodiment of the present invention. This embodiment can be applied to the performance test of the cable used by the server, determine the insertion loss of the cable, and detect whether the insertion loss of the cable meets the performance requirements of the server for the cable. The method can be executed by a cable testing device, which can be implemented in the form of hardware and / or software, and the cable testing device can be configured in an electronic device. The electronic device is used to perform performance tests on the cables used by the server. Figure 1 As shown, the method includes:

[0060] Step 101: Control the cable under test to transmit a test signal a preset number of times, and obtain a test insertion loss of the test signal during each transmission process.

[0061] Optionally, the cable under test is a cable that needs to be tested at the current moment. The cable under test includes two ports. The network analyzer connected to the cable under test may be a vector network analyzer. The network analyzer includes a signal output port and a signal input port. The signal output port is a port for outputting a signal. The signal output port of the network analyzer is connected to one port of the cable under test, and the signal input port of the network analyzer is connected to another port of the cable under test.

[0062] Optionally, the test signal is a signal set in the network analyzer that can be used to transmit through the cable under test. The test signal can be a digital signal or an analog signal. The frequency of the test signal is a preset frequency. Exemplarily, the preset frequency can be any frequency greater than 0 Hz and less than 50 GHz. The preset frequency can be 4 GHz, 8 GHz or 16 GHz.

[0063] Optionally, the network analyzer can output the test signal to the cable under test through the signal output port, so that the cable under test transmits the test signal to the signal input port of the network analyzer, thereby controlling the cable under test to transmit the test signal. Then the network analyzer can receive the test signal transmitted by the cable under test through the signal input port.

[0064] Optionally, a signal strength detection component is provided in the network analyzer. The signal strength detection component is a component used to detect the signal strength of a signal. Before outputting the test signal to the cable under test through the signal output port, the network analyzer can detect the signal strength of the test signal through the signal strength detection component to obtain the signal strength of the test signal in the initial state. Then, after the cable under test transmits the test signal to the signal input port of the network analyzer, the network analyzer can detect the signal strength of the test signal after being transmitted through the cable under test through the signal strength detection component.

[0065] Optionally, the test insertion loss of the test signal during each transmission process is the signal strength detected by the network analyzer that is lost during each transmission process of the test signal through the cable under test. For each transmission process, the difference between the signal strength of the specified signal detected by the network analyzer after being transmitted through the cable under test and the signal strength of the specified signal in the initial state is the test insertion loss of the test signal during the transmission process. The network analyzer calculates the difference between the signal strength of the test signal after being transmitted through the cable under test and the signal strength of the test signal in the initial state, and the test insertion loss of the test signal during the transmission process can be obtained. Exemplarily, the signal strength of the test signal in the initial state is 30dB, the signal strength of the test signal after being transmitted through the cable under test is 26dB, and the test insertion loss of the test signal during the transmission process is -4dB.

[0066] Optionally, the preset number of times is the number of times the cable under test is controlled to transmit the test signal and the test insertion loss of the test signal during the transmission process is obtained. The preset number of times can be set according to business needs. Exemplarily, the preset number of times can be 60. The network analyzer repeatedly executes the operation of controlling the cable under test to transmit the test signal and obtaining the test insertion loss of the test signal during the transmission process until the number of times the operation of controlling the cable under test to transmit the test signal and obtaining the test insertion loss of the test signal during the transmission process is equal to 60, and then feeds back the test insertion loss of the test signal obtained during each transmission process of the 60 transmission processes to the electronic device.

[0067] Optionally, controlling the cable under test to transmit a test signal a preset number of times, and obtaining a test insertion loss of the test signal during each transmission process, includes: sending a test start command to a network analyzer connected to the cable under test, so that the network analyzer repeatedly executes the operation of controlling the cable under test to transmit a test signal, and obtaining a test insertion loss of the test signal during the transmission process, until the number of operations of controlling the cable under test to transmit a test signal, and obtaining a test insertion loss of the test signal during the transmission process is equal to a preset number, and then feeding back the obtained test insertion loss of the test signal during each transmission process to the electronic device; obtaining the test insertion loss of the test signal fed back by the network analyzer during each transmission process.

[0068] Optionally, the test start instruction is an instruction for instructing the network analyzer to repeatedly execute the operation of controlling the tested cable to transmit the test signal and obtaining the test insertion loss of the test signal during the transmission process until the number of times the operation of controlling the tested cable to transmit the test signal and obtaining the test insertion loss of the test signal during the transmission process is equal to a preset number of times, and then feeding back the obtained test insertion loss of the test signal during each transmission process to the electronic device. The test start instruction includes the preset number of times.

[0069] Optionally, the cable under test is controlled to transmit a test signal to obtain a test insertion loss of the test signal during the transmission process, including: detecting the signal strength of the test signal through a signal strength detection component to obtain the signal strength of the test signal in an initial state; outputting the test signal to the cable under test through a signal output port so that the cable under test transmits the test signal to a signal input port of a network analyzer, thereby controlling the cable under test to transmit the test signal; receiving the test signal transmitted by the cable under test through the signal input port; detecting the signal strength of the test signal after being transmitted through the cable under test through a signal strength detection component; calculating the difference between the signal strength of the test signal after being transmitted through the cable under test and the signal strength of the test signal in the initial state, thereby obtaining the test insertion loss of the test signal during the transmission process.

[0070] Step 102: Determine an estimated insertion loss of the test signal in each transmission process according to a measurement error corresponding to the tested cable and a test insertion loss of the test signal in each transmission process.

[0071] Optionally, the estimated insertion loss of the test signal during each transmission process is the actual signal strength lost by the test signal during each transmission process estimated based on the measurement error corresponding to the cable under test and the test insertion loss of the test signal during each transmission process.

[0072] Optionally, the test interference factor may cause an error between the signal strength lost during the transmission of the signal detected by the network analyzer through the type of cable and the signal strength lost during the transmission of the real signal through the type of cable. The test interference factor may include the internal noise of the network analyzer used and human factors during the test. The measurement error corresponding to the cable under test is the error between the signal strength lost during the transmission of the signal detected by the network analyzer through the type of cable and the signal strength lost during the transmission of the real signal through the type of cable, which is calculated based on the historical test data of the same type of cable as the cable under test.

[0073] Optionally, before controlling the cable under test to transmit the test signal a preset number of times and obtaining the test insertion loss of the test signal during each transmission process, it also includes: obtaining a measurement error corresponding to the cable under test uploaded by a target user.

[0074] Thus, the estimated insertion loss of the test signal in each transmission process can be automatically determined based on the measurement error corresponding to the tested cable and the test insertion loss of the test signal in each transmission process.

[0075] Optionally, the target user may be a tester who is responsible for managing the performance test process of the tested cable. The target user calculates the measurement error corresponding to the tested cable based on the historical test data of cables of the same type as the tested cable, and then uploads the measurement error corresponding to the tested cable to the electronic device. The electronic device obtains the measurement error corresponding to the tested cable uploaded by the target user, and stores the measurement error corresponding to the tested cable in a local database.

[0076] Optionally, the estimated insertion loss of the test signal in each transmission process is determined based on the measurement error corresponding to the cable under test and the test insertion loss of the test signal in each transmission process, including: performing the following operations for each transmission process: determining the estimated insertion loss of the test signal in this transmission process based on the measurement error corresponding to the cable under test, the test insertion loss of the test signal in this transmission process, the estimated insertion loss of the test signal in the previous transmission process and a preset insertion loss estimation formula.

[0077] Therefore, the actual insertion loss of the test signal during the current transmission through the cable under test can be automatically estimated based on the measurement error corresponding to the cable under test, the test insertion loss of the test signal during the current transmission, the estimated insertion loss of the test signal during the previous transmission, and the preset insertion loss estimation formula. This facilitates determining the reliable insertion loss among all test insertion losses based on the estimated insertion loss, and thus accurately determining the insertion loss of the cable under test based on the reliable insertion loss, and detecting whether the insertion loss of the cable under test meets the server's performance requirements for the cable.

[0078] Optionally, determining the estimated insertion loss of the test signal in the current transmission process according to the measurement error corresponding to the tested cable, the test insertion loss of the test signal in the current transmission process, the estimated insertion loss of the test signal in the previous transmission process, and a preset insertion loss estimation formula includes: calculating the estimated insertion loss of the test signal in the kth transmission process according to the following preset insertion loss estimation formula:

[0079] X k =X k-1 +G k *(Z k -X k-1 ),

[0080]

[0081] Among them, X k is the estimated insertion loss of the test signal during the kth transmission, X k-1 is the estimated insertion loss of the test signal during the k-1th transmission process, G k is the coefficient in the preset insertion loss estimation formula, Z k is the test insertion loss of the test signal during the kth transmission process, is the measurement error corresponding to the measured cable, is the estimated error of the preset insertion loss estimation formula, k=1,2…N, N is the preset number of times. The k-1th transmission process is the previous transmission process of the kth transmission process. For the first transmission process of the test signal, the estimated insertion loss of the test signal in the previous transmission process may be -3dB. The estimated error of the preset insertion loss estimation formula may be the error between the estimated insertion loss estimated using the preset insertion loss estimation formula based on historical data statistics and the actual insertion loss. Exemplarily, the measurement error corresponding to the cable under test is -2dB, and the estimated error of the preset insertion loss estimation formula is -2dB.

[0082] Optionally, the preset insertion loss estimation formula is a formula for estimating the actual signal strength lost when the test signal is transmitted through the cable under test based on the measurement error corresponding to the cable under test and the test insertion loss of the test signal when it is transmitted through the cable under test.

[0083] Optionally, after calculating the estimated insertion loss of the test signal during the kth transmission, the value of the estimated error may be updated to the value of the current value of the estimated error plus (1-G k )

[0084] Step 103: Determine reliable insertion losses and unreliable insertion losses among all test insertion losses according to the test insertion losses and estimated insertion losses of the test signal in each transmission process.

[0085] Optionally, the reliable insertion loss is a test insertion loss with a small deviation that is not affected by the test interference factor. The unreliable insertion loss is a test insertion loss with a large deviation that is affected by the test interference factor.

[0086] Optionally, the preset difference threshold is a preset value. Normally, for each transmission process, if the test insertion loss of the test signal during the transmission process is not affected by the test interference factor, the deviation is small, and the difference between the test insertion loss of the test signal during the transmission process and the estimated insertion loss of the test signal during the transmission process will be less than the preset difference threshold. If the test insertion loss of the test signal during the transmission process is affected by the test interference factor, the deviation is large, and the difference between the test insertion loss of the test signal during the transmission process and the estimated insertion loss of the test signal during the transmission process will be greater than or equal to the preset difference threshold. Therefore, if the difference between the test insertion loss and the estimated insertion loss corresponding to the test insertion loss is less than the preset difference threshold, it indicates that the test insertion loss is not affected by the test interference factor and the deviation is small, then it can be determined that the test insertion loss is a reliable insertion loss. If the difference between the test insertion loss and the estimated insertion loss corresponding to the test insertion loss is greater than or equal to the preset difference threshold, it indicates that the test insertion loss is affected by the test interference factor and the deviation is large, then it can be determined that the test insertion loss is an unreliable insertion loss. Exemplarily, the preset difference threshold is 0.2dB.

[0087] Optionally, reliable insertion losses and unreliable insertion losses among all test insertion losses are determined based on the test insertion loss and estimated insertion loss of the test signal during each transmission process, including: performing the following operations for each test insertion loss: determining the difference between the test insertion loss and the estimated insertion loss corresponding to the test insertion loss, and detecting whether the difference is less than a preset difference threshold; if the difference is less than the preset difference threshold, determining that the test insertion loss is a reliable insertion loss; if the difference is greater than or equal to the preset difference threshold, determining that the test insertion loss is an unreliable insertion loss.

[0088] Therefore, the test insertion loss with a smaller deviation that is not affected by the test interference factors can be determined among all the test insertion losses based on the test insertion loss and the estimated insertion loss of the test signal in each transmission process. This makes it possible to accurately determine the insertion loss of the cable under test based on the test insertion loss with a smaller deviation that is not affected by the test interference factors, and detect whether the insertion loss of the cable under test meets the server's performance requirements for the cable.

[0089] Step 104: Determine the insertion loss and test result of the tested cable according to the reliable insertion loss.

[0090] Optionally, the insertion loss and test result of the cable under test are determined based on the reliable insertion loss, including: determining the average value of the reliable insertion loss as the insertion loss of the cable under test, and detecting whether the absolute value of the insertion loss of the cable under test is greater than a first preset value; if the absolute value of the insertion loss of the cable under test is greater than the first preset value, determining that the test result of the cable under test is unqualified; if the absolute value of the insertion loss of the cable under test is less than or equal to the first preset value, detecting whether the absolute value of the insertion loss of the cable under test is greater than a second preset value; if the absolute value of the insertion loss of the cable under test is greater than the second preset value, determining that the test result of the cable under test is qualified; if the absolute value of the insertion loss of the cable under test is less than or equal to the second preset value, determining that the test result of the cable under test is abnormal data.

[0091] Therefore, the insertion loss of the cable under test can be accurately determined based on the detected insertion loss with a small deviation that is not affected by the test interference factors, and based on the insertion loss of the cable under test and the preset value, it can be determined whether the insertion loss of the cable under test meets the server's performance requirements for the cable, and the test result of the cable under test can be obtained.

[0092] Optionally, the insertion loss of the cable under test is the signal strength lost during the transmission of the signal through the cable under test. Reliable insertion loss is the signal strength lost during the transmission of multiple groups of relatively accurate test signals through the cable under test. The average value of the reliable insertion loss is the signal strength lost during the transmission of the relatively accurate signal through the cable under test. Therefore, the average value of the reliable insertion loss is determined as the insertion loss of the cable under test, so as to accurately determine the insertion loss of the cable under test based on the insertion loss with a small deviation that is not affected by the test interference factors.

[0093] Optionally, the test result of the tested cable is qualified, unqualified or the data is abnormal. If the test result of the tested cable is qualified, it indicates that the insertion loss of the tested cable meets the performance requirements of the server for the cable. If the test result of the tested cable is unqualified, it indicates that the insertion loss of the tested cable does not meet the performance requirements of the server for the cable. If the test result of the tested cable is abnormal data, it indicates that the insertion loss of the tested cable is too small, the data accuracy of the insertion loss is abnormal, and the insertion loss of the tested cable needs to be remeasured.

[0094] Optionally, if the absolute value of the insertion loss of the cable is large, it indicates that the signal is greatly attenuated during the transmission through the cable, which will cause the quality of the signal transmitted through the cable in the server to decrease. The first preset value and the second preset value are two preset values. The first preset value is greater than the second preset value. The first preset value and the second preset value can be values ​​estimated based on the cable loss data or cable loss test report provided by the cable manufacturer. Under normal circumstances, if the absolute value of the insertion loss of the cable is less than or equal to the second preset value, it indicates that the insertion loss of the tested cable is too small, the data accuracy of the insertion loss is abnormal, and the insertion loss of the tested cable needs to be re-measured, then the test result of the cable can be determined to be data abnormal. If the absolute value of the insertion loss of the cable is greater than the second preset value and less than or equal to the first preset value, it indicates that the signal is less attenuated during the transmission through the cable, the quality of the signal transmitted through the cable in the server can be guaranteed, and the insertion loss of the cable meets the performance requirements of the server for the cable, then the test result of the cable can be determined to be qualified. If the absolute value of the insertion loss of the cable is greater than the first preset value, it indicates that the signal is greatly attenuated during the transmission through the cable, the quality of the signal transmitted through the cable in the server cannot be guaranteed, and the insertion loss of the cable does not meet the performance requirements of the server for the cable, then the test result of the cable can be determined to be unqualified. Exemplarily, the first preset value is 5 dB, and the second preset value is 1 dB.

[0096] Therefore, the test insertion loss and estimated insertion loss of the test signal in each transmission process can be automatically and intuitively displayed to relevant users through visual charts, so that relevant users can understand the test status of the tested cable in a timely manner.

[0097] Optionally, the electronic device may generate a visual chart for displaying the test insertion loss and estimated insertion loss of the test signal in each transmission process according to the test insertion loss and estimated insertion loss of the test signal in each transmission process through a chart generation component. The chart generation component is a component provided in the electronic device for generating a visual chart for displaying specified data according to specified data. The visual chart may be a table, a line chart, or a curve chart.

[0098] Optionally, sending the visualized chart to a target user includes: sending the visualized chart to a terminal device of the target user. The terminal device of the target user is a terminal device used by the target user.

[0100] Therefore, the insertion loss with small deviation and the test results of the tested cable detected during the cable testing process which are not affected by the test interference factors can be automatically provided to the relevant users, so that the relevant users can obtain the test data and test results in time.

The insertion loss of the cable can be determined, and whether the insertion loss of the cable meets the performance requirements of the server for the cable. The accuracy and reliability of the cable testing process are low. The real insertion loss of the test signal in each transmission process through the cable under test can be automatically estimated based on the measurement error corresponding to the tested cable and the detected insertion loss of the test signal in each transmission process through the tested cable. The insertion loss with a small deviation that is not affected by the test interference factors can be screened out from the detected insertion loss based on the estimated real insertion loss. The insertion loss of the tested cable can be accurately determined based on the insertion loss with a small deviation that is not affected by the test interference factors, and it can be determined whether the insertion loss of the tested cable meets the performance requirements of the server for the cable. The test result of the tested cable can be obtained, thereby improving the accuracy and reliability of the cable testing process.
